Overview: Anker's Vision for Whole-Home Energy
Anker has been building toward the E10 for years, and it shows. The SOLIX E10 system represents a fundamental shift in how Anker approaches backup power — moving from portable power stations to a modular, whole-home energy platform that can serve as a primary or secondary power source for an entire house.
The system consists of three core components: the E10 Power Module (which houses the inverter and controls), the B6000 battery modules (6 kWh each), and the Smart Generator 5500 (a tri-fuel backup generator that can recharge the system automatically). The Prime Off-Grid Kit includes the E10 module plus two B6000 batteries for 12 kWh total, the B6000 Extra Battery kit adds another 12 kWh, and you can scale up to a total of 90 kWh with multiple B6000 units.
Currently see current price on Amazon on Amazon for the Prime kit, the E10 sits at a higher price point than most competitors, but it also delivers capabilities that competitors can't match: 9,000W solar input, 10kW turbo output for central AC starting, and expandability to 90 kWh without any additional inverter hardware. For homeowners who want a true grid-independent system, the E10 is the most compelling option available from a major brand.
Key Features
12–90 kWh Modular Capacity
The E10's modular design is its defining feature. Unlike competitors that require a separate inverter upgrade for each expansion tier, the E10's Power Module handles everything from 12 kWh to 90 kWh without modification. You simply stack additional B6000 battery modules (each 6 kWh) and connect them with a single cable. Expansion from 12 kWh to 24 kWh costs roughly $3,000–$4,000 (the B6000 Extra Battery kit), compared to $5,000+ for equivalent expansion from EcoFlow or Tesla.
10kW Turbo Output — Central AC Compatible
The E10's turbo mode delivers 10kW of peak output (7.68kW continuous), enough to start and run most residential central air conditioning systems up to 5 tons. The 155–275 LRA (Locked Rotor Amps) startup rating covers small to medium central AC units, well pumps, and other high-surge appliances. This is a capability that most competitors in the $5,000–$8,000 range simply don't offer — they can run a fridge and lights, but not central AC.
9kW Solar Input for Rapid Recharge
With 9,000W of solar input capability (dual MPPT), the E10 can fully recharge its 12 kWh battery bank in just 1.3–2 hours of peak sun — or completely replenish from partial discharge in under an hour. This is more solar input than any competitor in its class and means the E10 can sustain near-continuous whole-home power even on partly cloudy days. For off-grid homes, this reduces the number of solar panels needed to maintain indefinite power.
Universal Generator Compatibility
The E10 works with Anker's Smart Generator 5500 (a 4,500W DC tri-fuel generator that runs on gas, propane, or natural gas) for automatic off-grid recharging. Critically, it also works with existing 120V/240V AC generators via a 9.6kW bypass — meaning you don't need to buy Anker's generator to use the E10. During a multi-day winter outage with limited solar, you can recharge from any portable generator while continuing to power your home.
Tool-Free Stacking + NEMA 4 Rating
The E10 system stacks vertically with a tool-free connection system — no wiring, no electrician needed for the stacking itself (you still need a licensed electrician for the transfer switch). The NEMA 4 weather rating means the system can be installed indoors (garage, basement, utility room) or outdoors in a sheltered location. The wall/floor mount options add flexibility for tight spaces.

Anker E10 vs. The Competition
The E10's most direct competitors aren't portable power stations — they're permanently installed home battery systems like the Tesla Powerwall 3 and the EcoFlow Delta Pro Ultra X. Here's how they compare at similar capacity levels:
| Spec | Anker E10 | EcoFlow DPU X | Tesla Powerwall 3 |
|---|---|---|---|
| Starting Capacity | 12 kWh | 12.3 kWh | 13.5 kWh |
| Max Expand | 90 kWh | 180 kWh | 40.5 kWh (3 units) |
| Continuous Output | 7.68 kW (10 kW turbo) | 12 kW | 11.5 kW |
| Solar Input | 9,000W | 10,000W | 5,000W |
| Portable? | Yes (modular) | Yes | No (permanent) |
| DIY Install? | Yes (transfer switch) | Yes | Professional only |
| Generator Compatible | Yes (9.6kW bypass) | Yes | Limited |
| Est. Price (12 kWh) | See price Price → | $7,999+ | $9,200+ |
The E10's key advantage over both the Powerwall and Delta Pro Ultra X is portability. Unlike the Powerwall, which is permanently wall-mounted and must be professionally installed (and left behind if you move), the E10 can be unplugged, loaded into a truck, and taken with you to a new home. For homeowners who may move within 10 years, this alone makes the E10 a better investment than a permanently installed system.

Frequently Asked Questions About the Anker SOLIX E10
Can the Anker SOLIX E10 replace a Tesla Powerwall?
In many ways, yes. The E10 offers similar capacity (12 kWh base vs. Powerwall 3's 13.5 kWh), comparable output (10kW turbo vs. 11.5kW), and better solar input (9kW vs. 5kW). The E10's key advantages are portability (take it when you move) and lower cost (see current price on Amazon vs. $9,200+). The Powerwall's advantages are integrated whole-home backup with seamless grid interaction and Tesla's established solar ecosystem. For most homeowners, the E10 offers a better value proposition, especially if portability matters.
How much does a full Anker E10 system cost?
The Prime Off-Grid Kit (12 kWh) is $5,999. Adding the B6000 Extra Battery for 24 kWh adds ~$3,000–$4,000. The Smart Generator 5500 adds ~$1,500. Professional transfer switch installation adds $400–$800. A complete 24 kWh system with generator backup costs approximately $10,000–$11,000 installed. At 90 kWh (maximum expansion), the system cost exceeds $30,000 — but you'd rarely need that much capacity unless you're fully off-grid.
Can I install the E10 myself?
The physical stacking and connection of E10 modules is tool-free and DIY-friendly. However, connecting the system to your home's electrical panel requires a transfer switch or interlock kit, which must be installed by a licensed electrician to comply with electrical codes and safety requirements. Never attempt to wire a generator into your panel yourself.
How long does the E10 take to charge?
On AC power (7,680W input), the 12 kWh system charges from 0–100% in approximately 1.2 hours. With 9,000W of solar panels in peak sun conditions, it can charge in about 1.3–2 hours. On a standard 120V household outlet (1,500W), expect 8–10 hours for a full charge. The AC charge speed is among the fastest available for a system of this capacity.
Is the Anker E10 eligible for solar tax credits?
The E10 system, when paired with solar panels for charging, may qualify for the federal solar Investment Tax Credit (ITC) of 30%. The battery storage alone can qualify if it's charged primarily from solar (at least 75% of annual charging from solar). Consult a tax professional for your specific situation. Some states offer additional incentives for battery storage systems.
